The Aqualux AIO Iron + Sulphur filter is a safe, easy, and chemical free way to remove iron, manganese, and sulphur from your rural water supply. This system will handle 15 ppm of combined iron & manganese, as well as dramatically reducing sulphur (rotten egg smell). The Aqualux AIO system uses air to oxidize out these contaminants, traps them in the filter bed, and backwashes them out automatically, all of which is controlled by the rugged and long-lived Fleck 2510SXT control valve. There's no better way to solve your iron, manganese, and sulphur problem. Set it and forget it!
